elevate the grain to a point to be conveniently and effectively severed by the cutting mechanism.

In developing the present improved grain lifting device, I have provided a structure which, to my mind, will better fulfill the requirements of an appliance of this class because of its peculiar construction and arrangement of parts, because said parts have been especially selected and mechanically corelated to form a device capable of accomplishing the grain lifting operation in a more dependable and satisfactory manner.

In the drawings Figure 1 is a view showing the complete grain lifting device in elevation and applied to the platform of a combine or harvester.

Fig. 2 is a top plan view of the structure seen in Fig. 1.

Fig. 3 is a bottom plan view thereof.

Fig. 4 is a perspective view of a renewable and removable panel.

Fig. 5 is a combined perspective view of two distinguishable parts of the under strap structure.

Fig. 7 is a perspective view'of the substantially V-shaped carrier frame for the panel.

Fig! 8 is a section similar to Fig. 6.

Fig. 9 is a further detail section, taken on the line 99 of Fig. 1.

One of the most important parts of the improved device is the hingedly mounted substantially V-shaped panel accommodating frame, denoted by the numeral 10 in Fig. 7. I have found it practical and expedient to construct this from a single length of wire of appropriate strength to provide an upper arm 11 and a lower arm 12, and the curved bight portion is distinguished by the nu- 50 meral 13.

The arm 12 is rigidly fastened to a strap 14 forming a part of the hinge construction, and it will be noted that the forward extremity of this strap 14 is curved and fastened in place as indicated at 15 to cooperate with the bight portion 13 in forming a sort of a shoe to ride along the ground 16 as indicated in Fig. 1.

On its under side, the strip 14 is provided with a shoulder forming lug 17 which serves a purpose to be hereinafter described. The arm 11 is slightly longer than the arm 12, and is bent partly asindicated at 18 to aid in maintaining the panel 19 in place. The extending extremity 20 of this arm forms a handle to facilitate application and removal of the panel. The panel isin the nature of a V-shaped wooden board having a marginal groove 21 in which the arms 11 and 12 are. seated.

This frame structure 10 as seen in Fig. 7, and the panel 19 as represented in Fig. 4,

' forms the principal forward and downwardly extending part of the lifting device, and

this device is hingedly mounted on the platform 22 of the harvester.

I now call attention to the numeral 23 which designates a stationary strap riveted or otherwise fastened to the under side of the platform, and terminating near the front end of saidplatform. This strap'23 cooperates with the strap 14 in that the adjacent ends are formed to provide a hinged joint such as is indicated at 24.

The numeral 25 represents a hanger bracket carried by the intermediate portion of a strap- 23 and provided with a guide pulley 26, over which an adjacent portion of the retention cable 27 is trained. This cable is attached at its inner end to a coiled spring 28 anchored on the adjacent end of the strap 23. Then the cable is passed through a guide eye 29 on the bolt 30 and through a second guide eye 31 on the lug 17. The front end of the cable is anchored to the front end portion of the strap 14 as indicated at the point 32. This cable, spring and pulley arrangement are designed to swing the entire frame and its panel down to a point to cause the shoe 23 to ride in contact with the ground 16.

Means is provided to limit the downward swinging of the shifting device, and this preferably comprises an arm 33 held in place by the bolt 30, underlying and bridging the hinge 24 and having its free end portion in a position to engage behind the shoulder 17. Thus, the lug 17 abutting the arm 33 serves to limit the downward swinging motion of the forwardly and downwardly inclined lifting device.

At the same time, upward bobbing and swinging is allowed to minimize resistance against the travel of the shoe 15; This upward swinging motion is, however, controlled by the spring pulled cable 27.

Consequently the spring and its cable tends to urge the shoe 15 into gliding contact with the ground, but the shoe is prevented from becoming embedded in the ground by the coacting stop elements 17 and 33.

Particularly do I wish to emphasize the arrangement embodying the resilient V- shaped frame 10 into which the panel board 19 is removably snapped, and retained in place. Then too, I place stress on the idea wherein the lower arm 12 of this frame is attached to the bar or strap 14- allowing this bar to reinforce the frame, and permitting the bar to have the additional function of a long leaf in the hinge construction. Moreover, the bent terminal 15 of the bar 14, allows it to partly shield the curved bight 13 and to at the same time form a free gliding ground engaging shoe.

The use of the elongated stationary leaf 23 of the hinge is important,'in that this constitutes a mounting for the bracket 25 carrying the guide pulleys as well as provides anchorage for the spring 28. Moreover, the bolt 30 serves to secure the strap 23 in place, carries the guide eye 29 and fastens one end of the stop arm 33 in its operative position.

Consequently all of the parts have been carefully selected and organized tov provide acomplete structural arrangement which will operate efiiciently and which is subject to repair when the board 19 becomes unduly warped. A constantly straight hingedly mounted free gliding grain lifting device is believed to be desirable to facilitate grain cutting.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several together with a reinforcing strap attached to the lower arm of the frame and having its frontal portion formed to provide a ground engaging glide shoe.
